Starts from the current visual reference and project constraints.

Build a patterns component named DarkModeToggle in React/Next.js.
Goal: recreate the same overall UI and behavior as the DarkModeToggle reference from a component gallery.
What it needs to communicate: Animated toggle switch for light/dark mode with size variants..

Project constraints:
- Use Next.js 16.2.6 with the App Router, React 19, TypeScript strict mode, and Tailwind CSS v4.
- Do not create a tailwind.config.js file. Use Tailwind v4 utilities and CSS variables where design tokens are needed.
- If you are implementing this inside the same project, use the Prompt font via next/font/google. If not, use the closest equivalent typeface.
- Return production-ready code with imports, responsive behavior, keyboard accessibility, and polished empty, hover, focus, active, and disabled states where relevant.
- Match the reference closely: color palette, spacing scale, border radius, shadows, icon scale, typography hierarchy, and motion timing.

Component-specific expectations:
- Build the full multi-part interaction, not just the outer shell.
- Preserve realistic spacing, affordances, and task flow.
- Avoid unnecessary dependencies unless the behavior truly requires them.
- No explicit color literals were found in the examples. Match the live reference and the project accent color when appropriate.

Props to support:
- initialMode: 'light' | 'dark' — default 'dark' — Starting mode
- label: string — Label text next to toggle
- size: 'sm' | 'md' | 'lg' — default 'md' — Toggle size
- className: string — Additional CSS classes

Reference usage patterns:
- No examples were documented. Infer a sensible default presentation and one richer usage example.

Feature expectations:
- Animated knob
- Sun/Moon icon
- Three sizes
- Accessible

Output requirements:
- Return complete code, not pseudocode.
- Include all necessary imports and helper types.
- Keep the implementation accessible, responsive, and visually finished.
- Match the reference for color, size, shape, typography, spacing, and interaction states as closely as possible.
- If multiple files are needed, organize them cleanly and explain the file structure briefly.

Tweak only product-specific copy or data after the first generation pass.
